The charge density on a disk of radius R = 12.2 cm is given by σ = ar, with a = 1.34 μC/m3 and r measured radially outward from the origin (see figure below). What is the electric potential at point A, a distance of 36.0 cm above the disk? Hint: You will need to integrate the nonuniform charge density to find the electric potential. You will find a table of integrals helpful for performing the integration. V

The charge density on a disk of radius R = 12.2 cm is given by σ = ar, with a = 1.42 μC/m3 and r measured radially outward from the origin (see figure below). What is the electric potential at point A, a distance of 42.0 cm above the disk? Hint: You will need to integrate the nonuniform charge density to find the electric potential. You will find a table of integrals helpful for performing the integration. Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. V
